Ability to activate smart crawl on a per site basis

Really wanting to activate smart crawl on a per site basis in my multi-site setup...but can't...which now forces me to have to piece together other plugins.

I realize there are some nifty network wide abilities, but the network managers should also be able to activate on a per site basis for special clients, or as pro-site tier.

It seems to be a disadvantage to block it to only network activation, can you please...remove forcing to network activation....please. Thanks!
